MARINE was a composite mode that ran both AIS and VDES decoders
simultaneously. It is now fully replaced by allocating two virtual
channels — one tuned to the AIS frequencies and one to VDES — each
decoded independently.
- trx-core/state: remove RigMode::MARINE variant
- trx-protocol/codec: remove MARINE parse/serialize
- trx-backend-ft817: remove MARINE from unsupported-mode guard
- trx-backend-ft450d: remove MARINE from FM CAT code mapping
- trx-backend-soapysdr: remove MARINE from bandwidth table, supported
modes list, AIS channel activity check, parse_rig_mode, vchan_impl
bandwidth table, demod selection, dsp/channel bandwidth / sample-rate
/ IQ-tap guards
- trx-server/audio: remove MARINE from AIS and VDES decoder activation
- trx-server/rig_task: remove MARINE from audio-streaming mode list
- trx-server/main: remove MARINE from bandwidth table, mode parser,
VDES channel subscription match
- app.js: remove isMarineMode(), MARINE entry in MODE_BW_SPECS, MARINE
bandwidth specs block in visibleBandwidthSpecs(), MARINE from
decoder status mode lists, MARINE BW-edge drag guard

Allow users to allocate multiple virtual channels independently of
browser tab count. Channels survive SDR center-frequency retuning as
long as they stay within the capture bandwidth; channels that fall
outside the SDR span are automatically destroyed.
Changes:
- trx-core: add AUDIO_MSG_VCHAN_DESTROYED (0x12) wire constant;
add default subscribe_destroyed() to VirtualChannelManager trait
- trx-backend-soapysdr: update_center_hz() detects OOB channels,
removes them, fires destroyed_tx broadcast; add destroyed_sender()
and subscribe_destroyed() override
- trx-server/audio: recv_destroyed() helper avoids select! busy-loop
for non-SDR backends; send AUDIO_MSG_VCHAN_DESTROYED to client when
a channel is evicted server-side
- trx-client/audio_client: persist active_subs across TCP reconnects,
re-subscribe on reconnect; handle AUDIO_MSG_VCHAN_DESTROYED by
pruning vchan_audio map and forwarding UUID via vchan_destroyed_tx
- trx-frontend/lib: add vchan_destroyed broadcast field to
FrontendRuntimeContext
- trx-client/main: wire vchan_destroyed_tx into audio client and
frontend runtime context
- trx-frontend-http/vchan: remove per-session one-channel limit in
allocate(); replace auto-evict in release_session_on_rig() with
subscriber-count-only update; add remove_by_uuid() for server-
triggered OOB destruction (skips redundant VChanAudioCmd::Remove)
- trx-frontend-http/server: spawn background task that forwards
vchan_destroyed broadcast to ClientChannelManager.remove_by_uuid()

Add VirtualChannelManager trait in trx-core::vchan with types VChannelInfo,
VChanError, and SharedVChanManager alias. Re-export from trx-backend::vchan.
Implement SdrVirtualChannelManager in trx-backend-soapysdr:
- Wraps Arc<SdrPipeline> + shared AtomicI64 center_hz
- add_channel / remove_channel / set_channel_freq / set_channel_mode
- Slot-stability: on remove, shifts pipeline_slot for surviving channels
- update_center_hz: recomputes IF offsets for all virtual channels on retune
- update_primary_meta: keeps channel-0 freq/mode in sync for API consumers
Wire into SoapySdrRig (holds Arc<SdrVirtualChannelManager>, exposes
channel_manager()), SdrPipeline (shared_center_hz AtomicI64), and RigHandle
(vchan_manager: Option<SharedVChanManager>). main.rs extracts the manager
before boxing the SDR rig and stores it in the handle.
Add max_virtual_channels to SdrConfig (default 4, TOML-configurable).
Add 5 unit tests: add, remove, permanent guard, cap, out-of-bandwidth.

Replace the fixed channel_dsps Vec (thread-owned) with an
Arc<RwLock<Vec<...>>> shared between the IQ read thread and the async
side, enabling live add/remove of virtual DSP channels.
Cache audio construction params in SdrPipeline so add_virtual_channel()
can build ChannelDsp instances without being re-passed them. Add:
- SdrPipeline::add_virtual_channel() / remove_virtual_channel()
- SoapySdrRig::virtual_channel_add/remove/set_freq/set_mode()
- SoapySdrRig::center_hz() / half_span_hz() accessors
The IQ read loop holds a brief read lock (~2 ms per block) while
processing all channels; write lock for add/remove waits at most one
block. All 27 existing tests continue to pass.

Two problems prevented reliable recovery after a persistent overflow:
1. Restart storm: once read_error_streak >= 3, every subsequent read
failure triggered a deactivate/activate cycle, potentially preventing
the hardware from stabilising. Fix: after a successful restart, reset
read_error_streak to 1 so the stream gets 2 more failures before the
next restart attempt.
2. Stuck-deactivated stream: if activate() failed after overflow, the
stream was left deactivated. Subsequent reads returned non-overflow
errors which handle_read_error ignored (Ok(false)), so the stream was
never reactivated. Fix: add a high-streak fallback (>= 10 consecutive
errors of any kind) that also attempts a full deactivate/activate
restart, covering the stuck-deactivated case.

Add frequency-selective attenuation of the L-R difference signal to
reduce stereo hiss on weak FM broadcasts. Uses the quadrature component
(diff_q) as a noise reference per US7292694B2 (Wildhagen/Sony).
The algorithm splits sum, diff_i, and diff_q into 6 overlapping subbands,
estimates per-band SNR from smoothed |diff_q|² noise power, and applies
an energy-weighted broadband gain to the original diff signal. This
preserves clean stereo content (<4 dB loss) while attenuating noise-only
diff channels (>6 dB reduction).
Enabled by default; toggled via set_denoise_enabled() / set_wfm_denoise().
